ABSTRACT

In this study, the toxicological/pharmacological research method of "quantity-weight-evidence" network was first proposed and practiced to supplement the existing methodology of network toxicology. We transformed the traditional qualitative network into a quantitative network in this study by attributing weights to toxic component content and target frequency, which improved the reliability of data and provided a research idea for the systematic safety evaluation and toxicological research of Chinese medicinal herbs. Firstly, 50% ethanol extract of Dysosma versipellis(DV) was administrated to rats via gavage and the potential hepatotoxic components were identified by serum pharmacochemistry. Then, the component targets were obtained from SwissTargetPrediction, PharmMapper and other online databases, and the target weights were given according to the relative content of components and target fishing frequency. Meanwhile, the targets of hepatotoxicity were predicted from online databases such as Comparative Toxicology Database(CTD) and GeneCards. Subsequently, protein-protein interaction analysis and KEGG pathway enrichment were performed with the STRING database. Finally, the quantitative network of "toxic components-weighted targets-pathways" was constructed. Eleven potential toxic compounds were predicted, including podophyllotoxin, podophyllotoxone, deoxypodophyllotoxin, and 6-methoxypodophyllotoxin. A total of 106 hepatotoxic targets and 65 weighted targets(e.g., Cdk2, Egfr, and Cyp2 c9) were identified. The results of Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment showed that these targets could act on PI3 K-AKT, MAPK, and Ras signaling pathways to play a role in inflammatory response and oxidative stress. However, traditional network toxicology showed that 51 targets such as AKT1, Alb, and Stat3 may lead to hepatotoxicity by mediating inflammation and cell proliferation. In conclusion, we proposed "quantity-weight-evidence" network toxicology in this study and used it to study the mechanism of DV-induced hepatotoxicity in rats. This study confirms the feasibility of this new methodology in toxicological evaluation and further improves the systematic evaluation of the safety of Chinese medicinal herbs.

ABSTRACT

OBJECTIVE@#To explore the effect of electro-acupuncture (EA) on glucose and lipid metabolism in unmarried patients with polycystic ovary syndrome (PCOS).@*METHODS@#Fifty-four PCOS patients were equally randomized into true acupuncture group and sham acupuncture group (control) for totally 16 weeks of treatment by random method with a computerized randomization program. Patients in true acupuncture group accepted traditional acupuncture methods with EA and two sets of acupoint groups were used alternatively. The first set consisted of Zhongji (CV 3), Qihai (CV 6), Guilai (ST 29), Sanyinjiao (SP 6), Yinlingquan (SP 9), Hegu (LI4) and Baihui (GV 20), and the second set consisted of Tianshu (ST 25), ST 29, CV 3, CV 6, SP 6, Taichong (LR 3), Neiguan (PC) 6 and GV 20. Patients in the sham acupuncture group accepted shallow acupuncture methods through EA without electricity at 4 non-meridian points in each shoulder and upper arm. Outcome measures included body mass index (BMI), waist-hip-ratio (WHR), oral glucose tolerance test (OGTT), insulin release test, glucose and lipid metabolism indicators such as total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, adiponectin, leptin, visfatin, resistin, and interleukin (IL-6).@*RESULTS@#Twenty-six subjects in the true acupuncture group and 20 subjects in the sham group completed the clinical trial. After 16 weeks of treatment, no significant difference in the outcome measures were observed between the two groups (P>0.05). However, as compared with baseline data, a reduction in weight, BMI, hipline, WHR, fasting glucose, homeostatic model assessment of insulin sensitivity, visfatin and HDL-C, and an increase in resistin and IL-6 were observed in the true acupuncture group (P<0.05). In addition, a reduction in visfatin and an increase in TC were also observed in the sham group (P<0.05).@*CONCLUSIONS@#Acupuncture may have a beneficial effect in the treatment of PCOS by improving glucose and lipid metabolism. Moreover, the sham acupuncture may be not completely ineffective. Sham acupuncture may improve some of the aspects of the glucose and lipid metabolism of PCOS patients through a placebo effect.

ABSTRACT

Objective:To investigate the efficacy of sequential therapy of CD19 and CD22 chimeric antigen receptor T cells (CAR-T) for relapsed/refractory mediastinal B lymphoblastic lymphoma (B-LBL).Methods:One patient with relapsed/refractory mediastinal B-LBL treated with sequential therapy of CD19 and CD22 CAR-T who was admitted to Tongji Hospital of Huazhong University of Science and Technology Tongji Medical College in March 2017 was reported. At 1, 3, 6, 12 and 18 months after CAR-T therapy, the indicators of primary disease remission were monitored and the relevant literature was reviewed.Results:The patient relapsed and progressed after third-line chemotherapy, and then received sequential therapy of CD19 and CD22 CAR-T. In the course of cellular immunotherapy, the patient presented grade 1 cytokine release syndrome. After active treatment, the patient got stable condition and was discharged. The patient came to the hospital for regular review, and the mediastinal mass of the patient was dynamically followed up. After CAR-T therapy, the mediastinal mass of the patient was significantly reduced, and the patient was in continuous remission for 18 months.Conclusions:Sequential therapy of CD19 and CD22 CAR-T provides a new therapeutic approach for relapsed/refractory B-LBL. For patients with poor curative effect of conventional chemotherapy, CAR-T therapy should be actively performed as soon as possible to improve the remission rate and the long-term prognosis of patients.

ABSTRACT

In this study, we explored the antibacterial effect and mechanism of dihydroartemisinin(DHA) combined with cefuroxime(CFX) or ampicillin against Escherichia coli. The minimum inhibitory concentration(MIC) of DHA, cefuroxime, and ampicillin against E. coli was 300,25,25 μmol·L~(-1), respectively, determined by broth microdilution method and 2,3,5-triphenyltetrazolium chloride(TTC) method. The minimum bactericidal concentration(MBC) was 25 μmol·L~(-1) for cefuroxime, above 600 μmol·L~(-1) for DHA. The fractional inhibitory concentration index(FICI) of DHA combined with cefuroxime or ampicillin was 0.375 and 0.75, respectively, determined by checkerboard microdilution assay, suggesting the synergistic effect or additive effect of the drug combination. Moreover, the time-effect curve showed that the antibacterial activity of DHA and CFX combination was much stronger than that of either of the drugs, suggesting that combination with DHA can decrease the CFX dosage. Then we studied the synergistic mechanism of DHA combined with cefuroxime and found that the combination of the two drugs had a significant inhibitory effect on the total protein bands, as shown by the results of polypropylene gel electrophoresis. The results of conductivity method and alkaline phosphatase test respectively showed that its conductivity value and alkaline phosphatase(AKP) leak were significantly higher than either of the drugs, suggesting that the integrity of bacteria may be damaged. The scanning electron microscope(SEM) results showed that the morphology of E. coli was destroyed most in the combination group. The quantitative fluorescence PCR technology showed that the combination of two drugs can inhibit the expression of superoxide stress gene soxS. In summary, the combination of dihydroartemisinin and cefuroxime has a synergistic antibacterial effect on E. coli.

ABSTRACT

Objective:To investigate the inhibitory effect and the possible mechanism of essential oil from fructus Alpinia zerumbet (EOFAZ) on endothelial-to-mesenchymal transition (EndMT) induced by high glucose (HG). Method:Human umbilical vein endothelial cells (HUVECs) was cultured in vitro to analyze the pharmacodynamic effects of EOFAZ on EndMT and oxidative stress damage induced by HG. The experiment was set the blank group, HG group (35 mmol·L-1), EOFAZ low dose group (1 μg·L-1) and EOFAZ high dose group (4 μg·L-1). After EOFAZ intervention for 2 h, HG was added to incubate for 72 h in order to establish EndMT cell model. Western blot was used to detect the protein expression of vimentin and platelet endothelial cell adhesion molecule (CD31). Angiogenesis experiment was used to detect the ability of cell migration ability in order to analyze the effect of EOFAZ on EndMT. The changes of reactive oxygen species (ROS) levels were detected by 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescence probe and the contents of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) in cells were detected by the kit method to analyze the effect of EOFAZ on oxidative stress. Western blot was used to detect the protein expression levels of nuclear transcription factor E2 related factor 2 (Nrf2) and Notch1. The overexpression of Nrf2 was achieved by adenovirus (AD) transfection and the mechanism of EOFAZ inhibiting EndMT was further analyzed. The experiment was set the blank group, HG group (35 mmol·L-1), AD-Nrf2 group, EOFAZ group (4 μg·L-1), AD-Nrf2+EOFAZ group (4 μg·L-1). The cells were infected with recombinant adenovirus overexpression plasmid of Nrf2 gene for 6 h, then replaced with normal medium for 24 h. After EOFAZ intervention for 2 h, HG was added to co-incubate for 72 h to induce EndMT. Western blot was used to detect the protein expressions of Nrf2, CD31, vimentin, Notch1 and Snail. Result:Compared with the HG group, after treatment with EOFAZ, the protein expression of CD31 was significantly up-regulated (P<0.05), the protein expression of vimentin was significantly down-regulated (P<0.01), the ability of cell migration was decreased (P<0.01), and the contents of ROS and MDA were decreased (P<0.05, P<0.01), the levels of CAT and SOD were increased (P<0.01). In addition, EOFAZ could significantly up-regulate the protein expression of antioxidant signal Nrf2 (P<0.01) and down-regulate the protein expression of Notch1 (P<0.01). High expression of Nrf2 was achieved by stable AD transfection into HUVECs. The results of Western blot showed that, compared with the HG group, the protein expression levels of Nrf2 and CD31 in each treatment group were significantly increased (P<0.01), while the protein expression levels of vimentin, Notch1 and Snail were down-regulated (P<0.01). At the same time, compared with the AD-Nrf2 group, the AD-Nrf2+EOFAZ group could further up-regulate the protein expressions of Nrf2 and CD31 (P<0.05, P<0.01), while decrease the protein expression levels of vimentin, Notch1 and Snail (P<0.01). Conclusion:EOFAZ ameliorates oxidative stress injury of vascular endothelial cells induced by HG and inhibits EndMT, which is related to Nrf2/Notch1 signaling pathway.

ABSTRACT

Objective:To evaluate primary retroperitoneal liposarcoma surgeries in combination with involved bowel resection .Methods:Clinical data of primary retroperitoneal liposarcoma patients admitted for surgery at Peking University International Hospital from Jan 2015 to July 2019 were retrospectively reviewed.Results:Twenty-four patients undergoing resectional surgeries combining with bowel resection were included for the study, of which 6 cases underwent right hemicolectomy, 8 did left hemicolectomy, 6 did sigmoidectomy, 2 did proctectomy and 8 did small bowel resection. The post operative morbidity was 38%. 2 of 24 had anastomotic fistula. There was no mortality. Final pathology disclosed well differentiated liposarcoma in 13 and dedifferentiated liposarcoma in 11 cases. 18 cases were confirmed with bowel infiltration pathologically. All patients were followed up after the surgery. After a median of 25 months following up, 8 cases developed recurrences and 3 deceased. Two-year overall survival and progression free survival probability were 91% and 71% respectively. Dedifferentiated liposarcoma as a pathological type was found as the only risk factor associated to poor progression free survival ( Z=2.02, P=0.042). Conclusion:Combining resection of primary retroperitoneal liposarcoma with involved bowel was relatively safe, with low morbidity, increasing tumor clearance. Dedifferentiated liposarcoma is associated wth poor prognosis.

ABSTRACT

OBJECTIVE@#To study whether pyroptosis is involved in the bilirubin-induced injury of primary cultured rat cortical microglial cells.@*METHODS@#Primary cultured rat cortical microglial cells were randomly administered with 30 μmol/L bilirubin (bilirubin group), 30 μmol/L bilirubin following 30 μmol/L VX-765 pretreatment (VX-765+bilirubin group), or an equal volume of dimethyl sulfoxide (control group). Modified MTT assay was used to measure the viability of microglial cells. Western blot was used to measure the expression of the pyroptosis-related proteins Caspase-1 and gasdermin D (GSDMD). Lactate dehydrogenase (LDH)-release assay was used to evaluate the cytotoxicity of microglial cells. EtBr/EthD2 with different molecular weights (394 Da/1 293 Da) was used to measure the size of plasma membrane pores. ELISA was used to measure the level of the inflammatory factor interleukin-1β (IL-1β) in culture supernatant.@*RESULTS@#After bilirubin stimulation, the viability of microglial cells decreased and LDH release increased, both in a time-dependent manner. Compared with the control group, the bilirubin group had a significantly higher positive rate of small-molecule EtBr passing through the cell membrane (P0.05). The expression of activated Caspase-1 significantly increased at 0.5 hour after bilirubin stimulation (P<0.05), and that of activated GSDMD significantly increased at 6 hours after bilirubin stimulation (P<0.05). The release of IL-1β significantly increased at 6 hours after bilirubin stimulation and reached the peak at 24 hours (P<0.001). Compared with the bilirubin group, the VX-765+bilirubin group had a significant increase in cell viability (P<0.05) and significant reductions in the expression of activated GSDMD, the pass rate of EtBr, and the release of LDH and IL-1β (P<0.05).@*CONCLUSIONS@#Pyroptosis is involved in bilirubin-induced injury of primary cultured microglial cells.

ABSTRACT

Objective: To provide the theoretical basis for determining the best harvesting plant organ and harvesting period, and investigate the content of chemical constituents of Callicarpa nudiflora in different plant organs and different growth periods. Methods: The contents of total flavonoids, total phenolic acid and total saponins were determined by ultraviolet spectrophotometry, and the seven components were determined by HPLC. The ANOVA and PCA methods were used to analyze the content of each constituent. Results: The dry extract rate, the contents of total flavonoids, total phenolic acid, total saponins, forsythiaside B, acteoside, isoacteoside, and apigenin-7-O-β-D-glucopyranoside in functional leaves were the highest, while the contents of caffeic acid, galuteolin and luteolin in tender leaves were the highest, and all of them were significantly different from the young shoots (P 0.05). The contents of total phenolic acid, total saponins, forsythiaside B, and acteoside were the highest in the FB period, and there was no significant difference with the EFS period (P > 0.05). The contents of galuteolin and apigenin-7-O-β-D-glucopyranoside were the highest in the earlier fruit maturation (EFM) period and the later fruit maturation (LFM) period, respectively, and there was no significant difference with the EFS period (P > 0.05). The contents of each chemical component were reduced to the minimum at the fruit-drop (FD) period, and it was significantly different from that at the EFS period and the FB period (P < 0.05). According to the comprehensive evaluation model constructed by PCA, the comprehensive score of the EFS period was the highest (F = 3.252), followed by the FB period (F = 3.011). Conclusion: Main chemical constituents of C. nudiflora were significantly different in harvesting parts and growth periods. The contents of main chemical constituents were higher in functional leaves and tender leaves, and the contents of main chemical constituents were higher from FB period to EFS period.

ABSTRACT

OBJECTIVES@#The epidemic of coronavirus disease 2019 (COVID-19) brought psychological stress to the public, especially to patients. This study aims to investigate the mental health of patients with COVID-19 in Changsha.@*METHODS@#We took cross-section investigation for the mental health of 112 patients with COVID-19 via questionnaires. Mann-Whitney test, Chi-square test, and Fisher's exact test were performed to compare general and clinical data between the slight-ordinary patients and severe patients. Single sample -tests were used to compare the difference between the factor scores of the Symptom Check-List 90 (SCL-90) in COVID-19 patients with the norm of 2015 and factor scores of SCL-90 in patients with the severe acute respiratory syndrome (SARS).@*RESULTS@#The obsessive-compulsive, depression, sleep and eating disorders had the highest frequency among the positive symptoms of SCL-90 in patients with COVID-19 in Changsha. The factor scores of somatization, depression, anxiety, phobia anxiety, sleep and eating disorders in patients with COVID-19 were higher than those of the norm (≤0.001 or 0.05).@*CONCLUSIONS@#The levels of somatization, depression, anxiety, phobia anxiety, sleep and eating disorders in patients with COVID-19 in Changsha are higher than those of the norm. However, the mental health of slight-ordinary patients with COVID-19 is better than that of patients with SARS. It needs to provide targeting psychological interventions depending on the severity of patients.
